What Is the Navy Federal Auto Calculator?

The Navy Federal Auto Calculator is a simple online tool that helps users estimate:

  • Loan Amount (after subtracting your down payment from the car price)
  • Monthly Payment (based on loan term and interest rate)
  • Total Interest (how much you’ll pay in interest over the life of the loan)
  • Total Payment (loan amount + total interest)

It’s perfect for Navy Federal Credit Union members—or anyone researching auto financing options—because it provides quick, accurate results without the need for complex math.

How Does the Calculator Work?

The calculator takes four key inputs:

  1. Vehicle Price – The total cost of the car you want to buy.
  2. Down Payment – The amount you’ll pay upfront to reduce the loan balance.
  3. Annual Interest Rate (%) – The yearly rate charged by the lender.
  4. Loan Term (Months) – The number of months you plan to finance your vehicle.

Once you hit Calculate, the tool uses a loan amortization formula to determine:

  • Monthly payments
  • Total interest over the life of the loan
  • The grand total you’ll repay

Example Calculation

Let’s say you’re buying a car for $25,000 with:

  • Down Payment: $5,000
  • Interest Rate: 4.5%
  • Loan Term: 60 months (5 years)

Results:

  • Loan Amount: $20,000
  • Monthly Payment: ~$372.86
  • Total Interest: ~$2,371.60
  • Total Payment: ~$22,371.60

This shows you’ll pay about $372.86 per month for 5 years, with a little over $2,300 in interest.

  2. Improve your credit score – Better scores = lower interest rates.
  3. Shop around – Compare offers from multiple lenders.
